Same satellite image returned for the last 4 hours

I have an application that gets both an IR4 and VIS satellite image for my location.  For the past few hours the same satellite image has been returned (clouds are not moving) but the time stamp on the image is updated.  

First, what is the frequency that I can expect a new satellite image is available (1 minute, 5 min, 10, 60 min) ???

Second, I don't like that fact that I am getting the same data in the image but the time stamp is changed .. yet my daily requests are being deducted.  I feel I am getting robbed.

It depends on where you are located.  In the US, we see new satellite images every 30 minutes, over some locations outside the US, images are less frequent, at worst, every 6 hours.

This was in the US.  So the same image for 4 hours seems like a problem.  Especially considering the fact that it has a time stamp on it.  How do I know if the image was actually updated before getting it and getting charged for it?

Can you provide the API URL?  What time was this issue encountered?

Here is the URL I was using:

http://api.wunderground.com/api/22135458cf131379/satellite/image.png?lat=35.560081&lon=-113.9095...

This happened between 4/27/2015 @ 14:05 and 4/27/2015 @ 19:39. I was requesting both VIS and IR4 and the same thing was happening for both.

Images were requested every 20 minutes because that is what I had discovered earlier was a good enough interval for my daily animations (would have preferred 15). I stopped requesting them after this because they were duplicated.  Looking at them today they seem fine, but I have not reviewed the full day.
